GUMMING APPARATUS FOR GIN-SAWS.

Application filed September 15, 1909.

Specification of Letters Patent.

Patented Dec. 31,1912.

Serial No. 517,826.

To all whom it may concern:

Be it known that I, EDWARD O. NnvnLs, a citizen of the United States,residing at Enterprise, in the county of Coffee and State of Alabama,have invented new and useful Improvements in Gumming Apparatus forGin-Saws, of which the following is a specification.

The present invention relates to gumming apparatus for gin saws, and theprimary object is to provide a structure, which may either be in theform of an attachment to a well known form ofgummer, preferably of thetype shown in the patent to Wood, No. 620,726, March 7, 1899, or mayconstitute an essential part thereof, said structure constitutingdriving means for the gumming mechanism that will permit a much fasterspeed with the same accuracy, and being much handier to operate.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of thegummer. Fig. 2 is a view in elevation of the opposite side. Fig. 3 is avertical cross sectional view on the line 3-3 of Fig. 1. Fig. 4, is adetail view showing the gearing connecting the gummer shaft with itsdriving mechanism.

Similar reference numerals designate corresponding parts in all thefigures of the drawlngs.

In the embodiment represented by the accompanying drawings, the gummlngmechanism, indicated generally by the reference numeral 4, and which maybe of a known type as aforesaid, includes a rotary gumming file 81 Fig.1, hereinafter termed the rotary gummer, carried by a shaft 82, Fig. 4,which is mounted in a gear frame 83 forming part of a main frame 5. Thismain frame includes a yoke 6 for straddling the space blocks bet-weenthe gin saws and also supports by means of an intermediate frame piece84 a transverse shaft 7 on which is mounted a sprocket wheel 8 and abevelgear 85 in mesh with the teeth of a beveled pinion 86, Figs. 2 and4, fast on said shaft 82 of the rotary gummer 81; whereby the rotationof said sprocket wheel is transmitted to said rotary gummer. The detailsof the gumming mechanism, which form no part of the present invention,will be more fully understood by reference to the'patent thereon, No.620,726, hereinbefore referred to. The within described drivingmechanism, including said sprocket wheel 8, and beveled gear 85 issubstituted for the hand crank shaft and beveled gear shown at Z, H andh in said patent.

Pivotally mounted on the lower portion of the main frame 5 is asupplemental frame, designated generally by the reference numeral 9.This supplemental frame includes a vertically disposed yoke 10, to whichare secured forwardly extending arms 11, said arms being bent inwardly,and disposed on opposite sides of the web 8* of the main frame, beingpivotally connected to said main frame, as shown at 12. Clips 13,connecting the arms 11 and extending on opposite sides of the web 8limit the swinging movement of the supplemental frame 9 with relation tothe main frame. A rod 14, pivotally mounted, as shown at 1 5 in the mainframe, has a sliding engagement in a collar 16 Figs. 2 and 3 carried bythe upper cross bar of the yoke 10, and mounted on this rod, is a coiledspring 17 one end of which abuts against the collar 16, the other endbearing against an abutment nut 18 on the rod. The lower cross bar 19 ofthe yoke 10 is provided with supporting spurs 20.

Journaled on a stud 21, carried by one side of the yoke 10, is a gearwheel 22, to which is fastened a handle crank 23, and this gear wheelmeshes with a pinion 24 on a shaft 25 that is journaled in the yoke, theshaft carrying a balance wheel 26 arranged in the yoke and a sprocketwheel 27. A sprocket chain 28 passes around the sprocket wheel 27, andthe sprocket wheel 8.

The saws of a gin being arranged face to face on a single shaft inalinement, in the usual manner with space blocks between adjacentblades, the saw gummer is applied to the saws one after another untilthe whole series has been gummed.

In using the device, the yoke 6 is arranged between the gin saws, uponthe saw supporting shaft or spacing collars, and the yoke 10 rests uponone of the frame beams of the machine, thus supporting the apparatus inproper relation to gum the saws. By operating the handle crank 23, itwill be obvious that the shaft 7 of the gumming mechanism will be drivenat a high rate of speed, and with comparatively little exertion on thepart of the operator after the mechanism is placed in operation, becauseof the balance or fly wheel 26. The slight pivotal movement allowedbetween the main frame 5 and the supplemental frame 9, together with theyielding connection between them,

5 serves at all times to maintain the sprocket chain 28 taut.

It will be obvious that the device is simple, and experience has 7demonstrated that it adds greatly to the usefulness of the gum- 10 mer.Furthermore it will be apparent that the structure may be employedeither as an attachment to machines already in use, or it may be made anessential part of the driving mechanism.

' 15 From the foregoing, it is thought that the construction, operationand many advantages of the herein described invention will be apparentto those skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

H ving thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A gin-saw gummer comprising a frame provided with a space-blockstraddling yoke, a rotary gummer, and mechanism for driving the gummercomprising a bevel gear wheel, a sprocket wheel and a shaft common tothe two in combination with a supplementary frame pivotally connectedwith the gummer frame, means for adjusting the supplementary frame onits pivot and yieldingly securing it in position, a sprocket wheelmounted on the supplementary frame, and asprocket chain connecting saidsprocket wheel with the sprocket wheel first named.

2. An attachment for a saw-gummer, comprising a frame detachably andpivotally secured to the said gummer and having an upright yoke providedwith depending supporting spurs, a rod connected to the gum mer andhaving a slidable engagement with the yoke, an abutmentarranged on therod and a coiled spring arranged around the said rod between theabutment and the yoke for yieldingly supporting the frame relative tothe gummer, and driving gearing journaled in the yoke of thesupplemental frame and adapted to be connected to the gummer mechanism.

In testimony whereof,I aiiix my signature in presence of two witnesses.V EDWVARD O. NEVELS. WVitnesses:
